206 roller too small?

[87-TURBO-T]

Wondering if my 206/206 roller will be too small for my goals. car is approx 3000 pounds, 235 cid, looking for a 9.90. fully ported GN1'S, champion race intake, turbo 66-67mm range, 120# injectors on E85.

its possible.....but yes the cam is a bit small for the goals.. your car weight is low and your on e-85. both of which will help for pushing a 9.xx

what if he bumped up to a 212/212?

 

[slimtastic]

a 212-212 is what id throw at it. with a 1.65 rocker

 

[Boost231]

why 1.65?

Its not too small but not ideal. If you have a max ported set of GN1's there is definite benefit to running more lift and faster ramp than any of the off the shelf grinds will offer. The type of lobe is just as important as the duration. If t were me id use it if i had it though. At that weight id be dropping to 3.23's for sure.

What would be optimal? I can sell the 206. thanks for the replies.

What mph are you reallylooking for? If you're planning on running 67 turbo I'd guess mid 140's at that weight. A custom cam with fast ramp and duration around 218@.050. 3.42 gear with 28.5- 29" tire.

I concure with this.
